Improved caster for furniture



UNITED STATES PATENT OEEIGE I-IEZEKIAH NAYLOR, OF PEKIN, ILLINOIS.

IMPROVED CASTER FOR FURNITURE.

Specification forming part of Letters Patent No. 58.879, dated October 16, 1866.

To all whom it may concern Be it known that I, HEZEKIAH NAYLOR, of Pekin, in the county ot' Tazewell and State ot' Illinois7 have invented a new and useful Improvement in Caster-Vheels for Furniture; and I do hereby declare that the following is a full, clear7 and eX'act description of the mode of constructing the same7 reference being had to the annexed drawings7 making part of this specification, in whieh- Figure l is a perspective view. Fig. 2 is a perspective view of the friction-balls 5 Fig. 3, a view of the bottom; Fig. 4, partly a side elevation and partly a section.

Thesame let-ters are employed in describing the same parts.

A represents the base ot' the caster or legy of the article of furniture, in which there is a chamber sufficient to receive the caster-ball B and friction-balls C. The caster-ball B protrudes through a circular opening in the base of less diameter than the ball. The caster-ball B rests against three friction-balls, C, which are placed at the angles ot an equilateral triangle, so as to revolve freely in their respective cavities, turning upon journals I), which sustain the weight of the article to which the caster is attached, by which means the friction of the caster-ball B in rolling is divided among the several journals, and the difficulty of moving the article to which the caster is attached greatly lessened.

I do not claim the use ot' a caster-ball, B, for that I know is not new; nor do I claim such a ball when supported upon frictionwheels, for I am aware that various arrangements for this purpose have been made; but

What Ido claim as my invention, and desire to secure by Letters Patent, is-

A caster in which the caster-ball B turns 011 three friction-balls7 C, which are placed in the angles of an equilateral triangle turning on journals which have bearings 011 both sides ot' said balls in recesses formed for the purpose in the top or" the caster7 substantiallyY as described.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.

HEZEKIAH NAYLOR.
